SeasonalityAdults have been collected in Alberta in August and September. IdentificationA large (3.5 - 4.0 cm wingspan) grey-brown Abagrotis. Head and body grey-brown, unmarked. Forewings essentially unmarked except for the prominent narrow rectangular reniform partially filled with black scales (nearly obsolete in some specimens) and the paler terminal area. Hindwings unmarked sooty brown, slightly darker than the forewings. Antennae filiform. Sexes similar. Very similar to A. erratica, which is browner, has the post-median line indicated by a series of fine dots, and has biserrate, bifasciculate male antennae. Keys to the species of Abagrotis and illustrations of adults and genitalia of both sexes are presented in Lafontaine, 1998.

There is a single annual brood in Alberta, with the adults flying in fall. The larvae are pale grey with elongated subdorsal spots on all abdominal segments. Larvae prefer the flowers of fruit trees in preference to the leaves, and are sometimes serious pests in orchards further west. Adults are attracted to both lights and sugar baits.
Conservation Uncommon in southern Alberta; common and sometimes an agricultural pest elsewhere. Diet Info No Alberta data; elsewhere recorded from apple (Malus), peach and cherry (Prunus), Saskatoon (Amelanchier), cottonwood (Populus), Boxelder (Acer negundo) and grape (Vitis). Range
Mainly southwestern North America, but extending eastward across the plains and with a large disjunct population in dune habitats in the southern Great Lakes area. It extends into western Canada only in the southern…
